In Astrobiology lecture, we have discussed life…Continue

All of these species are very well suited towards their particular environment, but if one were to put a camel in Antarctica, or an emperor penguin in the Gobi…Continue

To a FAR lesser degree it is almost like trying to come up with a standard definition of a hamburger. Is it two separate bread buns with a beef patty in the center?
